weather-related phenomenon, which generally is self-
correcting as the weather changes.
BRISKNESS OF FIRE: The hotter the fire in your stove,
the hotter your chimney and, therefore, the stronger the
draft.
BREAKS IN THE VENTING SYSTEM: An unsealed
clean-out door at the bottom of the chimney, leaky
stovepipe joints, a poor stovepipe-to-thimble connection,
missing caps, or a leaky chimney may cause inadequate
draft.

Excessive Draft
SEASONAL FACTORS: Early fall and late spring are
generally difficult seasons in which to establish proper
drafts. The colder the outside air is (relative to room
temperatures) the stronger the draft.
Operating the Stove
There are days when a draft is not easily established. As
outlined above, seasonal factors or a cold chimney may be
the cause. Try starting the fire by using small kindling and
fuel to obtain a quick, hot fire. Tend the fire frequently
with small fuel until the chimney is hot and the draft is well
established.
SOLUTIONS
Fully open the primary air control one minute before opening doors.
Preheat the chimney when first starting a fire.
Examine the chimney and stovepipe for blockage or creosote
accumulations.
Reline the chimney to the appropriate diameter
Install a draft inducer or replace the chimney.
Lengthen the chimney.
Seal chimney connections and openings in clean-out doors.
Disconnect all other appliances and seal openings.
Fully open the primary air control one minute before opening the
door and keep it fully open for a few minutes after reloading.
Burn the stove at a higher burn rate.
Install a chimney cap.
Empty ash pan more frequently.
Close the door tightly or replace the gaskets.
Slide ash grate to closed position.
Check the installation. Operate at LOW BURN. Install stovepipe
damper.
Reseal the stove with furnace cement.
Shorten the chimney. Install stovepipe damper.
Reline the chimney to the proper diameter.
Install a chimney cap.
Draft in excess of 0.1 wc should be corrected with a stovepipe
damper
Use only air-dried wood, preferably dried at least one year.
Operate the stove at a higher burn rate.
Replace with a pre-fabricated insulated chimney system or a
properly sized masonry chimney.
Reline or insulate the chimney.
Check the installation.
Caulk windows, seal openings in home.
Do not over-fire the stove. Monitor stove temperatures. Use
seasoned wood only.
Check the DRAFT. A damper may be required. Operate the stove
at a LOW BURN range.
